PHP - Updating Query
Hi all, for my website ive got a fuel station which ive coded so users can fill up there there car fuel tanks, but the code all works part from one part of it.
The code: The part of the code which isnt working: <?php $usermoney = $fetch->money; $costs2 = $fetch_fuelstation->price * $fueldiff; if ($costs2 > $usermoney){ echo "You dont have enouth money."; } elseif ($costs2 <= $usermoney){ $nmoney = $usermoney - $costs2; mysql_query("UPDATE users SET money='$nmoney' WHERE username='$username'") or die (mysql_error()); } ?> Ive got a varibal called $usermoney which selects the users current money from the database, but what im trying todo is take the fuel price away from there current money, but its not subtracting the money as it should. Anyone see why its not taking the money? Thanks. Similar Tutorialswhy is it not updating? <?php $_POST['email']; $_POST['submit']; if (isset($_POST['submit'])) { /*$sql =" UPDATE class_members SET email ='".$_POST['email']."', WHERE S_UID ='".$_POST['mem_id']."'

At the minute i have a page where i can add a new topic to a database, but i want to be able to update the query on another page if that makes sense So as an example say i have this below thats just been inserted into the database with an ID of 2. <?php // Details $id = $_POST['id']; $title = $_POST['title']; $detail = $_POST['detail']; mysql_connect("localhost", "web148", "123") or die(mysql_error()); mysql_select_db("web148") or die(mysql_error()); mysql_query("SET names 'utf8'"); mysql_query("INSERT into sunnyargues(ID, title, body) VALUES ('2', ''超级马里奥意大利再遭种族歧视', '当被问及在友谊赛上的不友好一幕会不会重演时,曼奇尼说,“有这种可能性。” “我当然不希望这样的事情发生,但是谁也不能保证。”'"); echo "<h1>Article Updated!</h1>"; ?> On the sunny argues page i currently have, where it only selects ID 1: <?php mysql_connect("localhost", "web148", "123") or die(mysql_error()); mysql_select_db("web148") or die(mysql_error()); mysql_query("SET names 'utf8'"); $result = mysql_query("SELECT body FROM sunnyargues WHERE ID='1'"); $row = mysql_fetch_array( $result ); echo nl2br($row['body']); ?> Is there a way i can update this query with the new ID of the 2nd article once its been inserted into the database. I hope that makes sense Hi there. I'm totally new (about a week!) with php and mysql and am encountering a problem that perhaps someone can help me with?
I've looked through to see if a similar problem has appeared or been solved, but without success, so apologies if I am repeating something.
In php I am trying to update 7 fields from a form from which a user has edited/modified any of the fields in a chosen record (except id).
Here is the code:
$id=$_GET['id']; Hello all, I'm relatively new to all of this, but making progress.... I figure this has come up before, but couldn't fin anything by search or browsing. I have an sql table that is cron updated every two minutes from externally generated data in table X columns a,b,c,... . As part of more complicated site, I have one body element page (selected by a tab in the header) that does various sql queries on the data in table X and displays the data. I need this to rerun the queries and update the displayed results every 2 minutes or so as well. However, the standard solutions do not seem to be working: <META HTTP-EQUIV="refresh" CONTENT="15"> A refresh button refreshes the entire site, and not just this element. <FORM> <INPUT TYPE="button" onClick="history.go(0)" VALUE="Force Flight Data Refresh"> </FORM> I hope it is clear. Any ideas of how I could get this to work? Thanks, Kalle Here is a snippet of the code on that page for what it's worth... </head> <body> <div id="header"> <center><h2><font color="red">TRAFFIC INFORMATION</font></h2> </div> <div id="navigation"> </div> <div id="content"> <!-- refresh button --> <FORM> <INPUT TYPE="button" onClick="history.go(0)" VALUE="Force Flight Data Refresh"> </FORM> </center> <?php $IDS->db_build($db); $IDS->db_query($db,$res,"SELECT * FROM `Pilots` WHERE `dest`='KORD'"); echo "<h5>Arrivals to O'Ha </h5>"; while ($arr_row = mysql_fetch_assoc($res)) { echo "<font color=yellow>".$arr_row['callsign']."</font> using route: ". $arr_row['route']."<br>"; } //end queries //close connect to sql database mysql_close($con) </div> <div id="footer"> </div> </body> </html> I have a form that allows my client to update some products. Now the products are simple just basic info and 1 picture. I have set this up so they can edit the products and change the information, having done this many times in the past, but now hit a puzzling block that I am baffled. The client when editing is presented with the form with the information pulled from the database and the form fields loaded with that data ready to edit. The image can either be left alone or they can choose to upload a new image. They are shown the image they currently have stored in the database. The problem I have is EVEN if they decide not to upload an image and change other information, when the submit the form it must be sending a blank value for the image somewhere as it is updating the database and removing the image reference as if it has been removed. I have an if/else statement based on the form to perform 2 different queries for the update in mysql. Here is the code for the form update, as you can see the image should not update??

Hello all,
Based on the suggestion of you wonderful folks here, I went away for a few days (to learn about PDO and Prepared Statements) in order to replace the MySQLi commands in my code. That's gone pretty well thus far...with me having learnt and successfully replaced most of my "bad" code with elegant, SQL-Injection-proof code (or so I hope).
The one-and-only problem I'm having (for now at least) is that I'm having trouble understanding how to execute an UPDATE query within the resultset of a SELECT query (using PDO and prepared statements, of course).
Let me explain (my scenario), and since a picture speaks a thousand words I've also inlcuded a screenshot to show you guys my setup:
In my table I have two columns (which are essentially flags i.e. Y/N), one for "items alreay purchased" and the other for "items to be purchased later". The first flag, if/when set ON (Y) will highlight row(s) in red...and the second flag will highlight row(s) in blue (when set ON).
I initially had four buttons, two each for setting the flags/columns to "Y", and another two to reverse the columns/flags to "N". That was when I had my delete functionality as a separate operation on a separate tab/list item, and that was fine.
Now that I've realized I can include both operations (update and delete) on just the one tab, I've also figured it would be better to pare down those four buttons (into just two), and set them up as a toggle feature i.e. if the value is currently "Y" then the button will set it to "N", and vice versa.
So, looking at my attached picture, if a person selects (using the checkboxes) the first four rows and clicks the first button (labeled "Toggle selected items as Purchased/Not Purchased") then the following must happen:
1. The purchased_flag for rows # 2 and 4 must be switched OFF (set to N)...so they will no longer be highlighted in red.
2. The purchased_flag for row # 3 must be switched ON (set to Y)...so that row will now be highlighted in red.
3. Nothing must be done to rows # 1 and 5 since: a) row 5 was not selected/checked to begin with, and b) row # 1 has its purchase_later_flag set ON (to Y), so it must be skipped over.
Looking at my code below, I'm guessing (and here's where I need the help) that there's something wrong in the code within the section that says "/*** loop through the results/collection of checked items ***/". I've probably made it more complex than it should be, and that's due to the fact that I have no idea what I'm doing (or rather, how I should be doing it), and this has driven me insane for the last 2 days...which prompted me to "throw in the towel" and seek the help of you very helpful and intellegent folks. BTW, I am a newbie at this, so if I could be provided the exact code, that would be most wonderful, and much highly appreciated.
Thanks to you folks, I'm feeling real good (with a great sense of achievement) after having come here and got the great advice to learn PDO and prepared statements.
Just this one nasty little hurdle is stopping me from getting to "end-of-job" on my very first WebApp. BTW, sorry about the long post...this is the best/only way I could clearly explaing my situation.
Cheers guys!

For example, if I do Code: [Select] $sql = 'My query'; $rs = mysql_query($sql, $mysql_conn); Is it then possible to run a second query on this data such as Code: [Select] $sql = 'My query'; $secondrs = mysql_query($sql, $rs, $mysql_conn); Thanks for any help Say I have this query: site.com?var=1 ..I have a form with 'var2' field which submits via get. Is there a way to produce: site.com?var=1&var2=formdata I was hoping there would be a quick way to affix, but can't find any info. Also, the query could sometimes be: site.com?var2=formdata&var=1 I would have to produce: site.com?var2=updatedformdata&var=1 Is my only option to further parse the query? I'm trying to update every record where one field in a row is less than the other. The code gets each row i'm looking for and sets up the query right, I hope I combined the entire query into one string each query seperated by a ; so it's like UPDATE `table` SET field2= '1' WHERE field1= '1';UPDATE `table` SET field2= '1' WHERE field1= '2';UPDATE `table` SET field2= '1' WHERE field1= '3';UPDATE `table` SET field2= '1' WHERE field1= '4';UPDATE `table` SET field2= '1' WHERE field1= '5'; this executes properly if i run the query in phpMyAdmin, however when I run the query in PHP, it does nothing... Any advice? here's the code: Code: [Select] $companyName = 'big company'; $address1 = 'big bay #8'; $address2 = 'some big warehouse'; $city = 'big city'; $province = 'AB'; $postalCode = 'T1T0N0'; $phone = '0123456789'; $email2 = 'bigKahuna@bigKahuna.edu'; $query = "INSERT INTO clients ( companyName, address1, address2, city, province, postalCode, phone, email) VALUES ( ". $companyName.",".$address1.",".$address2.",".$city.",".$postalCode.",".$phone.",".$email2.")"; $result = mysql_query($query, $connexion); if ($result) { // Success! echo "Fabulous! check the DB, we did it! :D<br>"; ?> <pre> <?php print_r($result); ?> </pre> <?php } else { // Fail! echo"CRAAAAAPP! something went wrong. FIX IT! :P<br>"; echo mysql_error(); } if (isset($connexion)) { mysql_close($connexion); } i copied it over from an old *working* file to illustrate how a simple INSERT works. this is the error i get: Code: [Select] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'company,big bay #8,some big warehouse,big city,T1T0N0,0123456789,bigKahuna@bigKa' at line 4 looks completely valid to me. all the database table elements are set to VARCHAR(80), so it can't be a space/type issue... halp! WR! What would be the correct way to close a mysql query?

What would cause this behavior - when I populate session vars from a MYSQL query, they stick, if I populate them from an MSSQL query, they drop. It doesn't matter if I get to the next page using a header redirect or a form submit. I have two session vars I'm loading from a MYSQL query and they remain, the two loaded from MSSQL disappear. I have confirmed that all four session vars are loading ok initially and I can echo them out to the page, but when the application moves to next page via redirect or form submit, the two vars loaded from MSSQL are empty.

This code works to delete the order but doesn't update the feeds section. All this is new to me so far and i think i am getting the hang of it. Should i still be using the quantity=quantity-:quantity or is there another way to do it with PDO? Sorry, i posted this in the wrong forum. Hope someone here can help until it's moved Edited by Self_Taught_Still_Learning, 30 May 2014 - 03:30 PM. So, I am making a CMS for my school and I am having some trouble. It's a magazine sort of CMS and what I want is that when you click on a certain thing it continues onto the next page. Through the CMS you can create pages - when you do this each page gets a unique PID. To access the pages you have to enter the PID on the end of the URL, e.g. : http://www.myschool.com/magazine/index.php?pid=x. What I need is a code that when an image gets clicked the PID number in the URL goes up by one. Thanks |
